Abstract (en)
[origin: WO0128520A1] The invention relates to compositions in the form of microemulsion preconcentrates that contain (a) a mixture that consists of a medium-chain triglyceride and an omega-9 fatty acid and/or an omega-6 fatty acid; and (b) a surface-active component that contains a polyoxethylene tenside. When contacted with water or with an aqueous medium these microemulsion preconcentrates form microemulsions. The microemulsions of the O/W type have an average particle size below 150 nm, preferably below 100 nm. The inventive microemulsion preconcentrates and microemulsions are suitable for use as vehicles for substances, namely active agents, that are hardly soluble in water, but soluble in components (a) and/or (b). In the aqueous phase, said microemulsions may contain water-soluble substances.
